ALFRED H. WHATLEY, OF PROVIDENCE, RHODE ISLAND, ASSIGN OR TO NEW ENGLAND MOTOR COMPANY, INCORPORATED, A CORPORATION 0F RHODE ISLAND.

ENGINE.

Application led October 26, 1925. Serial No. 64,884.

To all whom t may concern: y

Be it known that LALFRED H. WHATLEY, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island,- have invented lcertain new and useful .Improvements in Engines, of which the following is a specification.

My invention relates particularly to engines or motors in which opposed groups of cylinders drive the shaft or shafts through an oscillatory'frame or yoke adapted to receive its immediate impulse from the pistons.

Certain objects' of my invention are to convert the rectilinear motion of the reciprocating pistons to an oscillatory motion of the yoke, and to rotary motion of the shaft in a manner that will'reduce strain or tension upon the yoke bearings, crossheads and crank disks; and to afford a more positive ldrive through the operating parts of the engine.. y e 'f A further objectfis to avoid-a construction requiring the. employmeiitfanywhere in the eng1ne of `sphericall members seated in spherical or hemispherical` cups or bear-ings, whereby an accurate" fitting of the parts is extremely expensiae and "usually impossible.

Further objects-and 'advantages of the invention will be'apparent as it is better understood from the-following specification.

My invention consists in such parts and l in such combinations of parts as fall within the scope of the'l appended claims.

In theaccompanying drawingsv which form a part of this specification and which illustrates the principle of this invention in the best mode now known to me of applying this principle, .Y

Figure 1 is a side elevation of an internal combustion engine of the opposed cylinder type in which myginvention isembodied,

Figures 2 andI horizontal and vertical sections of the sanfeo'n lines 2-2 of Figure 1, and 3-3 of Figure 2 respectively,

Figures 4 and 5, transverse sections of the same on lines 4-4 and 55 respectively of Figure2, and

Figure 6,-a section on line 6-6 of Figure 5.

Like reference characters indicate like parts throughout the views.

The engine is supported in a casing comprising a body section 10 comprising a bottom or base 11, sides 12, and ends 13, said ends `being provided centrally with extensions l5. The casing is completed by a top section 17 fixed to the body section and extensions by bolts 18. Rotatably mounted in bearings 20 and 21 in the sections 15 in alignment with each other are a power driving shaft 23 and a second shaft 24 respectively. Journaled in the extensions 15 above the bearings is a single shaft 26. At both sides of the extensions 15 the ends 13 are cut away to allow the passage of pistons, as at 28. At these points are fixed to the ends 13 by bolts 30 four engine cylinders 32, 33, 34 and 35, all lying in the same horizontal plane and in the plane of the shafts 23 and4 24. The first two cylinders are opposed to the second two. 4These cylinders are of uniform construction with casings 36 and 'pistons 37, piston rods 38 rigid with the pistons. The adjacent ends of the two pairs of` piston rods, which are in alignment with each other, are connected by crossheads 40, slidable on guide rods 41 extending from the opposite cylinders through holes 42 in the heads. The crossheads have cavities 44 in their ends in which are rigidly fixed by pins `45` or otherwise the adjacent ends of the piston rods. `Transversely of each crosshead is a boreor cylindrical opening 47 in which slides an exteriorly .cylindrical block or bushing 48 with a transversely rectangular longitudinal passage 49 across which extends a pin or pivot member 50` lixed at its ends in the block.

Upon the adjacent ends of the shafts 23 and 24 are crank disks 52 and 53 respectively of similar construction. Each has a counterweighted peripheral extension 54 opposite a transverse eccentrically disposed bore or cylindrical opening 55, in wh1chv is slidably mounted a cylindrical block or bushing 56 identical in shape, operation and detailed construction with 'the bushings 48, and carrying similar pivot members 57 disposed transversely of their longitudinal passages.

The Voscillatory member through which ymotion is transmitted from the pistons to the shafts comprises an open substant-iall vcircular frame 60 provided with diametrically opposite aligned bores 62 in which are fixed intermediate their lengths rods or pins forming peripheral arms 64 and havin sleeves 65 upon their outer ends lpivoted upon the members 50 with their ends in contact with the walls of the openings 49. The inner ends of these rods form a divided diametrical bearing 66. Diametrical bores 67 in the frame, at right angles to the bores 62, have fixed therein rods or pins 69 forming arms provided upon their outer ends with sleeves 70 loose on the pivot members 57. The bearing 66 is loose in a diametrically disposed sleeve 72 having trunnions 74 mounted in the bores of vertical tubular posts or bosses 7 6 upon the portions 1l and 17 of the casing.

The rectilinear reciprocation of the two pairs of rigidly connected piston rods imparts from the pistons circular reciprocatory motion to the frame 60 in a horizontal plane, while the freedom of the sleeve 72 upon the rigid pins 64 permits such movement of the frame in a vertical direction as to permit the ins 69 to describe cones while rotating the disks 52 and 53 to drive their respective shafts 23 and 24.

A balance wheel 78 is in this instance shown on the shaft 23. The iston driving mechanism may be operated from either of the shafts 23 and 24. In this instance a ear 80 on the shaft 24 drivesa gear 82 on t e shaft 26 which is rovided with cams 84 for actuating the va ve stems 86 in any usual or convenient manner.

It will be noted that in the construction shown noV spherical or hemispheric'al bearings are required in the mountinor of the frame 60, nor in the connections of the frame with the other portions of the engine mechv anism, and that such connections are absent in every art of the engine. The absence of joints o such a character materially reduces the cost of engine construction, and the character, combinations, and arrange ment of parts whereby the employment of such connections are avoided makes the drive more positive and lessens the strain upon the yoke bearings, crossheads, and crank disks.
